Class 10 Science | Factors Affecting Upthrust

Science and Technology, Grade 10, Unit 8

Factors Affecting Upthrust

Density · Volume displaced · Archimedes' principle

By the end of this lesson you can

🧪

Show that upthrust grows with the density of the liquid

📦

Explain that upthrust grows with the volume displaced

📜

State and verify Archimedes' principle

🧮

Calculate upthrust using U = Vρg

🫒Edible oil

Density 0.90 g/cm³

Higher balance reading

Smaller upthrust

💧Water

Density 1 g/cm³

Lower balance reading

Greater upthrust

The notes are free to read in full.

Presenter notes: Today we find out when the upward push of a liquid is big and when it is small, and how Archimedes measured it exactly.
